    Restore the global xx* symbols and add them to wfbrename.h.
    
    I don't think they're ever used, but it's best to just leave them alone for ABI
    compatibility.

    Hide or rename more global symbols to avoid clashes with libfb.
    
    Rename composeFunctions, xxSetup, and xxPrintVisuals.  Hide the other xx*
    symbols by making them static.

    Use DrawablePtrs instead of PixmapPtrs for Prepare/Finish access.
    
    Also, define some wfb functions even if FB_ACCESS_WRAPPER is not defined.  This allows a client to use libfb and libwfb at the same time.

    Wrap libwfb memory access.
    
    Use the READ and WRITE macros to wrap memory accesses that could be in video
    memory.  Add MEMCPY_WRAPPED and MEMSET_WRAPPED macros to wrap memcpy and
    memset, respectively.

    Switch to using void* pointers.
    
    Pass the size of the data pointed to by src or dst as an argument to
    wfb{Read,Write}Memory.  This allows one set of macros to be used with any size
    pointer.  Assumes that sizeof(FbBits) >= sizeof(FbStip).

    Add framebuffer access wrapper infrastructure.
    
    Create fbPrepareAccess macros to call into the driver to set up the
    wfbReadMemory and wfbWriteWemory pointers.  Call these from fbGetDrawable and
    fbGetStipDrawable.
    
    Add the READ and WRITE macros, which expand to simple memory accesses for fb,
    and calls through the function pointers for wfb.
    
    Add fbFinishAccess macro to give the driver an opportunity to clean up.  Add
    calls to this in the appropriate places.

    Prefix all of the exported symbols in libwfb.so with "wfb".
    
    For now, just #define all of the exported symbols in wfbrename.h.  Later,
    we should add FBPREFIX() around the exported symbols and use -fvisiblity=hidden
    to hide the rest.

    Build infrastructure for libwfb.so.
    
    Builds fb/* twice, defining FB_ACCESS_WRAPPER for libwfb.la.  Define a macro,
    FBPREFIX(X) which expands to fbX for libfb.la and wfbX for libwfb.la.  Use the
    macro on [w]fbModuleData so the new module loads.
